Spilomena foxii Ckll. 



One 9, San Pedro, July 16 (W. P. and T. D. A. Cockerell). 



The only other record, that of the unique type, is Santa Fe, 

 N. M. (T. D. A. Cockerell). 



Stigmus fulvipes Fox. 



Three 9 9 found burrowing in a sandbank at San Pedro, July b 

 (W. P. and T. D. A. Cockerell). Only the unique type from 

 LosAngeles, Cal. ^D. W. Coquillet), was heretofore known. 



Notogonia nigripennis occidentalis n. subsp. 



?.— Length 16 mm. Differs from the typical form by the 

 smoother sculpture and short longitudinal impressed line on each 

 side of dorsulum, by the duller and more finely sculptured scutel- 

 lum and by the medial longitudinal impression of the postscutellum. 

 The flagellum is approximately as long as head and thorax. The 

 flagellum of N. cequalis is distinctly longer than the head and 

 thorax, measuring 10 mm. in the type (9) and consequently 

 2 mm. longer than length of head and thorax (8 mm.). 



The only specimen of N. nigripennk heretofore recorded is the 

 unique type in Coll. Am. Ent. Society, from " New York." This 

 is a most interesting find, and shows how little we know of the dis- 

 tribution of certain species.

 Cerceris provancheri D. T., Wien. Ent. Zeit., IX, 1890, p. 204. 

 One d, La Jolla, August, at flowers of Erujonum fasciculaium. 



It is evident from Provancher's description that he described a c^ 



and not a 9 . 



Cerceris cockerelli n- sp- 



Entire tegument strongly, more or less closely punctured. 



c^.- Length 7.5 mm. Clypeus dullish with small punctures and 

 large, close, somewhat indistinct punctures, the rest of the face 

 below the insertion of antenna with large, rather indistinct punc- 

 tures more separated than on clypeus, the spaces between the punc- 

 tures minutely punctate; area in the middle of the face broad, flat 

 anteriorly, abruptly and decidedly keeled posteriorly between the 

 insertion' of antenna, the face below antennae covered with a close, 

 fine, silvery pubescence and sparser longer hairs, head above the 

 antenna with strong, separated punctures, the space between them
